When entry is selected (in controls.js) it calls select_entry which in
turn ignores elements with class 'informal':

  select_entry: function() {
    this.active = false;
    value = Element.collectTextNodesIgnoreClass(this.get_current_entry(), 'informal').unescapeHTML();
    this.updateElement(value);
    this.element.focus();
  },

It should probably be parametar or just documented :-)
